h v invented a certainnew and use- Imp-royement in Smoke-Consuming De-.vices, whereof the; following is a specifica- 131011, reference beinghad to the. accompanynfildrawings v a v 4 I0, y invention relates-toboilers and coinmeans whereby thesteam generated thereingis superheatedin a retort adjacent to the boiler furnace, and injected below ,the coalfire in the furnace, with the air supplied to the latter, and directedin a above said; fire, whereby the smoke arising from said fire isforcibly mixed and consumed with the injectedfluid.

scribed is embodied in an internally fired boiler, and includes anannular retort in 'terp osedbetween the boiler furnace and the boilertubes, out of contact with the fuel,

' and so arranged that the steam traversing a passageway in the walls ofsaid retort is superheated by the gases of combustion in contact withsaid walls and being directed by said retort to the boiler tubes.-
